Materials in GeoDict can contain all material properties that are needed for simulations in GeoDict. For setting up ElastoDict simulations correctly, you have to define the mechanical properties of the materials that make up the structure.

In the GeoDict Material Database different linear and nonlinear materials are stored to set a the mechanical properties. A selection of standard materials is already predefined, but the true strength of the database is that it allows the user to define additional materials to be used in GeoDict simulations. More information on editing and using the GeoDict Material Database is available in the Material Database User Guide.

In the following sections the usage of nonlinear models and custom material laws are discussed. For how to incorporate predefined materials in ElastoDict, please refer to Constituent Materials.

In ElastoDict, several types of nonlinear material laws are integrated. The next section explains how these material laws can be set up.

Additionally, it is also possible to implement user-defined material laws through the UMAT interface.
